$150 Open-Source Attachment Turns the iPhone into a Thermal Imaging Camera
Modder Andy Rawson needed an easy way to find air leaks in his 100-year-old house in order to improve its energy efficiency. Not wanting to spend thousands of dollars on a thermal imaging camera, he decided to go the DIY route. He built a box containing a 64-zone temperature sensor, and managed to connect the device to his iPhone via the dock. By overlaying the temperature data onto the iPhone's camera display, the $150 attachment instantly turns the iPhone into a cheap thermal imaging camera.
